Randomized Controlled Trial Clinical TrialUltrasound-guided nerve block for inguinal hernia repair: a randomized, controlled, double-blind study.
Open inguinal hernia repair in adults is considered a minor surgical procedure but can be associated with significant pain. We aimed to evaluate acute postoperative pain management in male adults randomized to receive an ultrasound-guided ilioinguinal and iliohypogastric nerve block administered before surgery, in addition to a standard analgesic regimen. ⋯ Ultrasound-guided blocks of the ilioinguinal and iliohypogastric nerves resulted in a statistically significant and clinically relevant reduction in postoperative pain in the PACU both at mobilization and at rest.

Randomized Controlled TrialRandomized study of the effect of local anesthetic volume and concentration on the duration of peripheral nerve blockade.
Ultrasound guidance reduces the required local anesthetic volume for successful peripheral nerve block, but it is unclear whether this influences block duration. We investigated the ropivacaine volume and concentration effect on interscalene block duration. ⋯ Block duration is influenced by both local anesthetic volume and concentration, a finding of increasing relevance with the current trend to lower volumes for ultrasound-guided regional anesthesia.

The sensory territory of the lateral cutaneous nerve of the thigh as determined by anatomic dissections and ultrasound-guided blocks.
A femoral block sometimes fails to provide complete sensory anesthesia of the anterior aspect of middle and distal thigh, and a block of the lateral cutaneous nerve of the thigh (LCN) is often necessary to supplement it. The goal of this study was to demonstrate, both in the anatomy laboratory and in the clinical setting, a possible contribution of the LCN to the innervation of the anterior thigh. ⋯ Our results, coming from a small sample, seem to indicate that the LCN may contribute to the innervation of the anterior thigh in some cases. A block of the LCN could be considered when a femoral block has failed to produce the expected area of anesthesia.
